[DoctrineBundle] Fixed proxy generation with Doctrine >= 2.2.0

Bug fix: yes
Feature addition: no
Backwards compatibility break: no
Symfony2 tests pass: yes

The issue here was, that the name of the generated Proxy files have changed in Doctrine 2.2.0, thus the autoloader in the DoctrineBundle stoped working.

This PR fixes this issue by applying different string manipulations to the given class name depending on the currently used Doctrine version.

Can you squash your commits before I merge? Thanks.

Should I open a new PR when squashed the commits? Because I don't know what happens when I force the remote repository to push my squashed commits.

First you should rebase (normally), then squash and push with `--force`, then GH will automaticaly update this PR (if you push into same branch on which bases this PR).

Yeah I knew about the ```--force``` option. I just wasn't sure what happens when I do it. Thank you!

[FIX]fixed timezone bug in DateTimeToTimestampTransformer

After several trials, I found out that the original code

```php
$dateTime = new \DateTime(sprintf("@%s %s", $value, $this->outputTimezone));
```
would create a DateTime object with timezone being '0000', even though $this->outputTimezone is set to my local timezone.

so I expanded the code a bit and it's working now.

PHP Test code,

```PHP
$d = new DateTime("@1234567890 Asia/Tokyo");
echo date_format($d, 'Y/m/d H:i:s')."\n";
echo $d->getTimezone()->getName()."\n";

$d = new DateTime("now Asia/Hong_Kong");
echo date_format($d, 'Y/m/d H:i:s')."\n";
echo $d->getTimezone()->getName()."\n";
```

The output is as followed:
2009/02/13 23:31:30
+00:00
2012/03/13 03:35:55
Asia/Hong_Kong

This could be a bug of PHP,
